Description
The TS27x2 series are low-cost and low-power
dual operational amplifiers designed to operate
with high-voltage single or dual supplies. These
operational amplifiers use the ST silicon gate
CMOS process, providing an excellent
consumption-speed ratio thanks to three different
power consumptions, making them ideal for low-
consumption applications:
I
CC
= 10 µA/amp: TS27L2 (very low power),
I
CC
= 150 µA/amp: TS27M2 (low power) and
I
CC
= 1 mA/amp: TS272 (high speed)
The devices also offer a very high input
impedance and extremely low input currents.
Their main advantage compared to JFET devices
is the very low input current drift with temperature
(Figure 3).
